It took Lexus ~15 years to develop "structural blue", a colorless paint that creates blue light using this structural interference. The making-of video[2] is pretty amazing, and definitely worth watching.
This was all I could really find, unfortunately...
This is absolutely worth a read, and the less than 5 minutes to watch the video.

I'm not sure what the "Structural Blue Edition" cost (my guess is the range of $10K - $30K premium), but it's still far from the most expensive car paint jobs -- Porsche's "Liquid Metal Silver" for the 918 Spyder (created by BASF) was a $64,000 option (where the aluminum flakes arrange themselves in a specific way during application), yet there's been crazier stuff offered than that.
Moonstone sometimes exhibits red-orange coloration due to its structure of alternating layers of different types of feldspar. Opals do the same thing but by water-filled fractures inside a group of quartz spheres. We can synthesize both so making a structural red should not be difficult.
